Lung Cancer in Focus: Diagnosis, Treatment, and Future Directions
Lung cancer remains one of the most significant global health challenges, affecting millions of people each year. It develops when abnormal cells grow uncontrollably in the lungs, interfering with normal breathing and oxygen exchange. Smoking is the leading risk factor, but long-term exposure to air pollution, occupational hazards, and genetic susceptibility also contribute. Lung cancer is broadly classified into non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), each requiring different management approaches.
